Carstens offered not only the usual range of accessories - chucks, collets, steadies, taper-turning attachments and toolposts of various kinds - but also a beautifully engineered powered milling attachment that mounted onto a vertical slide. It was equipped with a 1340 rpm 0.18 kW 220 /380 V motor and employed a spindle able to accept boring tools up to 13 mm in diameter. The head was able to be swivelled through 360°, could be fitted on either side of the main casting and, because it was intended for relatively heavy-duty work, was driven at slow speeds though worm-and-wheel gearing. As a further refinement, for the cutting of splines and similar indexing work, a small plunger unit was provided that bolted to the changewheel bracket and allowed an ordinary gear to be used for the necessary dividing and spindle locking.A toolpost grinder was also offered: a powerful unit, it's only drawback was the rather large motor.It is likely that the maker would also have offered an alternative, direct-drive high-speed head able to accept small end mills, slot drills and grinding stones secured by a draw-in collet arrangement.
